Burning PSX Games

Depends on what you have on the computer. If you are frtunate enough to have the .BIN/.CUE file pair, then you need to burn it back to CD-R (not CD-RW) with CDRWin.

It might work. Idally you should know its origins (whether it is from the same region as your PS) and you'll need a modchip to play the backup.
